The project would expand the hotel's total accommodations to 860 rooms.

The 15-story tower, which would rise next to the existing 24-story hotel, will feature 365 guest rooms in addition to amenity spaces. The expansion would result in a total of 860 guest rooms at the Universal City Hilton, making it one of the largest hotels in Los Angeles County.

Since revealing the proposed tower in December 2017, Sun Hill has been engaged in discussions with project neighbors, according to Mark Davis, the company's President and Chief Executive Officer. "From the beginning, we have made it our priority to listen to and be considerate of our neighbors regarding our expansion plan," said Davis. "So when our neighbors shared thoughtful comments about our project, it motivated us to take a look at our plans and refine our proposal to further reduce neighborhood impacts."

LARGE Architecture, best known for the recently-completed Argyle House development in Hollywood, has been tapped to lead the redesign. A rendering of the revised project shows a contemporary glass tower featuring a rooftop amenity deck and a second outdoor space carved into the building's side.

According to a previous release by the developer, the project is expected to be up for approval at the Los Angeles City Council in 2019.

Record-breaking growth in tourism over the past seven years, as well as the arrival of new attractions at Universal Studios Hollywood, has driven other nearby hotels into expansion mode as well. The owner of the Sheraton Universal, which sits next door to the Hilton, recently filed plans with the City of Los Angeles to construct a 31-story, 551-room hotel on the property.
